The Ultra 10 pack is designed for self-supported runs that take competitors through mountainous terrain and unpredictable weather.
The Ultra 10 was designed to endure one of the toughest trail races on earth: the Ultra Trail du Mont Blanc. This year, our most rugged vest gets an upgrade with even lighter materials and a 2-litre reservoir that delivers more water with every sip. This pack is designed for self-supported runs that take competitors through mountainous terrain and unpredictable weather. It's engineered to hold everything on the UTMB packing list, including food, shed layers, a headlamp, trekking poles, maps and more. The custom-fit harness and dual sternum straps adjust for a stable, comfortable fit, and the cargo compression lets you cinch everything down to minimize bulk.
3D MESH: Lightweight, cushioned mesh maximizes airflow and reduces chafing for a cooler, more comfortable run.
CRUX RESERVOIR: Includes a Crux reservoir, which delivers 20% more water per sip, with a self-sealing bite valve and ergonomic cap.
